Nyob rau hauv kev lag luam Automotive kev lag luam, automotive aluminium nplooj ntawv yog heev nrhiav tom qab rau lawv cov kev tiv thaiv corrosion zoo heev. Qhov no muaj zog corrosion yog ze ze rau ib qho zoo - batanced alloying txheej txheem thiab kev ua haujlwm siab.
Aluminium nws tus kheej muaj ib qho℃ntawm corrosion tsis kam, kev sib sau sai sai rau cov pa oxygen ntxiv. Cov cuab yeej no yog txhawb ntxiv ntxiv los ntawm kev ntxiv ntawm ntau cov ntsiab lus rau hauv automotive aluminium nplooj ntawv. Magnesium, ib qho kev sib txuas ua ke hauv kev kho tsheb cov ntawv nyeem, txhim kho cov ntawv muaj zog thiab corrosion tsis kam. Nws tsim cov kuab muaj nrog txhuas hauv alloy, hloov kho cov qauv grain, thiab txhim kho kev ruaj ntseg ntawm oxide zaj duab xis. Manganese ua tau zoo ua kom tau cov ntawv tiv thaiv kev ntxhov siab thaum tsim kev cuam tshuam tsis zoo ntawm kev tsis zoo xws li ntawm corrosion tsis kam.
Silicon tseem ua lub luag haujlwm tseem ceeb hauv kev kho tsheb liag aluminium sheet alloys. Tus nqi uas tsim nyog ntawm silicon conforon confectes daim ntawv txheej txheem Casting thiab siab- lub zog. Nws tseem ua cov silicon -} aluminium compound nrog cov xim tawv, txhim kho nws hnav thiab corrosion tsis kam. Tsis tas li ntawd, thaum tooj liab tuaj yeem txo cov corrosion resistance ntawm aluminium daim ntawv rau ib qho zoo, nws tuaj yeem txhim kho nws lub zog thiab kub ua kom tau. Tuam txhab uas zoo ua kom zoo alloy formulas kom muaj kev sib npaug ntawm lub zog thiab corrosion tsis kam yuav tsum tau ua.
Ntxiv nrog rau cov ntsiab lus zoo tshaj plaws, cov txheej txheem ntau lawm rau cov khoom lag luam aluminium no kuj muaj qhov cuam tshuam zoo heev rau nws corrosion tsis kam. Cov txheej txheem cua sov ua kom muaj kev faib tawm ntawm cov khoom sib txawv, txuas ntxiv ua kom zoo rau cov ntawv microstructure thiab ua kom haum corrosion. Tsis tas li ntawd, cov txheej txheem kho deg xws li anodizing thiab electrophing txheej nyob rau hauv ib qho corrosive ib puag ncig xws li cov kua ntshav hnyav thiab cov tshuaj ntsev.
Qhov muaj zog corrosive ntawm kev kho tsheb cov ntawv txhuas yog qhov tshwm sim ntawm kev tsim qauv ntawm kev tshawb fawb keeb kwm thiab kev tsim kho tshiab hauv cov txheej txheem ntau lawm. Ob yam no ua haujlwm ua ke kom ntseeg tau tias Automotive Aluminium daim ntawv tswj tau lub teeb txawb kev txhim kho thiab nthuav nws lub neej pabcuam.
